The Holy Spirit didn't reveal that to you, that was personal bias and convictions of your own. It opposes your own belief system on repentance and the very fabric of your reality and relationship with God. So naturally, you showed repulsion to it. God's grace to those with some traditional backgrounds on repentance are offended. They think its downright blasphemous.
Yet, it isn't. It is Christ exalting. However, with the traditional understanding of sin confession and repentance one must trample underfoot the Son of God. Especially if one maintains that sin confession maintains one's salvation. For what reason did Christ die? Are we not justified? Then what forgiveness is sought and to what end? Our sins have experienced remission by the blood of Christ. VVhy do we seek another avenue for forgiveness other than Jesus' sacrifice? It doesn't make sense.
I can assure you, the Lord didn't reveal that to you (that he preaches a false gospel). Grace777x70 preaches the truth on God's grace and its sufficiency. He may, indeed, preach another gospel than the one you believe as far as repentance goes and how one has victory over sin, but you believe in the same Jesus Christ. You both believe in Jesus' death and resurrection and that we are saved by grace through faith. The process of sanctification, however, may be where there is a difference in methodology. Know this though, sanctification isn't what saves us. VVe are justified by faith.
